To all whom it may concern:

Be it known that we, WILLIAM G. LEROH and CHAUNGEY P. WHISLER, citizens of the United States, and residents of Akron, Ohio,

have invented certain new and useful'Improvements in HeeLTrimmers, of which the following is a specification.

Our present invention relates toan improved device or apparatus for trlmming the rind, lip, or flange from the edge of molded heels and it is designed more espe-- cave spherical surface, and also one at the edge of the convexspherical surface, and the present machine is designed toafiord a simple, economical, and efficient device by which these rinds or flanges may be expeditiously and smoothly trimmed.

The invention includes the novel features of construction and arrangement and combination of parts hereinafter described and particularly defined by the appended claims.

An embodiment of our invention is illustrated in the accompanying drawings, in Which, A

Figure 1 is a front elevation.

Fig. 2 is a side elevation partly broken away.

Fig. 3 is a view of a modification.

Referring by reference characters to this drawing the numerals 1 and 2 designate coacting cutting disks or shear cutters, which are designed to trim the flange or rind from the heel, said heel being indicated in trimming position at H, in Fig. 2, and the projecting rind ath. The rotary cutting disks or knives 1 and 2 are mounted upon parallel shafts 3 and 4, which may be supported 50.

and driven in any convenient manner, not necessary to be disclosed herein. The heel H during the trimming operation is supported upon a table 13 having a part spherical surface corresponding in curvature to the curvature'of the face of the heel. This table 13 is supported upon a swinging frame I 5, which has its side arms 5 connected by sultable pivots 6 and 6 to the supporting uprights 12 and 12 carried by a suitable base. The axes 6 and 6 are arranged in axial alinement with the meeting edges of the cutters andthe edge of the table indicated at k is also brought into close'prox-- imity to the meeting edge of the cutters,

as clearly shown in Figs. 1 and 3. By reason of this arrangement the frame 5 and with it the table may be shifted to any convenient angle with relation to the cutters while at the same time the edge of the table is maintained atexactly the same distance from the working edge of the cutters or in other'words in the same desired close proximity to the cutting point.

In order to maintain the frame in any position to which it may be adjusted we connect to a suitable part of the frame 5, as

for instance one of the arms 5 by a suitable p1vot connectlon 7, a rod 8, which rod extends through a pivoted boss 9 carried by a standard part or post 11. The rod can be released to.slide in the boss for the adjustmerit of the frame,v and be locked to hold the frame in its adjusted position by means of i I the set screw 10.

The table 13 is supported upon a portion of the frame of substantially inverted U- shape as indicated at 5 the side portions 5- being spaced widely enough apart to clear the lower cutter 2.

In trimming the rind from the molded heel the frame 5 carrying the table 12 is swung to such a position that the included angle formed by the conical face of the cutter 1 and the convex face of the table 13 is equal to the included angle of the concave faceof the heel and the edge of the heel, so that at all times the heels will be presented to the cutters so as to properly trim the rind or flange close to the body of the heel without cutting into the heel or damaging the same. When the frame has been properly adjusted it is locked-in position by'the rod 8 and thereafter the operator places the heel upon the table, rotates and slides the heel over the same in such a manner as to present the heelrind or flange progressively to the cutters.

For trimming the flange from the convex edge of the heel we employ a table having a convex seat as indicated at 13 in Fig. 3

lit?

and in this form of table we prefer to make vit of only part circular form as being more convenient for the manipulation of the heel.

What we .claim is: 1. In a device of the class described a pair of co-acting cutters, a table having a smooth unobstructed surface curved slightly in all directions, over which an article having a corresponding face may be freely moved in all directions, and means for adjustably supporting said table and mainl taining its edge in close proximity to the I meeting point of said cutters.

2. In a device of the class described a pair of co-acting rotary cutters, a.- frame pivoted on an axis coincident with the meeting point of the cutters, a table having a curved surface terminating in a narrow having arms pivoted on an axis coincident with the meeting point of the cutters, a supporting table carried by said frame having a curved surface terminating in proximity to: said meeting point, a rod'pivotally con nected to said frame, and a stationary part to which said rod is'adjustably connected.

4L. In a device of the class described, a pair of superposedrotary coacting cutters, a frame piv'oted on an axis coincident with the meeting point of the cutters,- said frame comprising arms depending from their pivots and horizontal portions and a portion of inverted U-shape supported by the horizontal portions, saidfinverted U-shaped portion being of greater width than and in alinement with the lower cutter and a table supported by said inverted U-sha'ped portion.

' In testimony whereof, we aflix our signatures. 1 y
